Electricity: Home-security systems



AppliancePartsPros.com, Inc.

Introduction

Homeowners have a multitude of security systems and products from which to choose. Some products are simple and only need a screwdriver for installation. Some systems are more complicated and require installing wiring. Always fol low the manufacturer’s installation instructions.

Security systems can be hardwired or wireless. Hardwired systems operate using low-voltage wire and circuits. Typical system components include the master control panel, backup batteries, control keypads, door and window sensors, motion detectors, smoke and heat detectors, a siren, a phone dialer and a key-chain remote control. Sophisticated systems may also include sensors for monitoring water intrusion, freezing temperatures and carbon monoxide.

A wireless system consists of many of the same components as the hardwired systems. However, the wireless sys tern uses radio frequency signals to monitor the components, many of which are separately powered by batteries or plug into a receptacle outlet.

You’ll also have a choice of alarms: A silent alarm automatically dials a police station or security company, often for a monthly fee, whereas on-site alarms may take the form of piercing sirens and flashing lights. A system may have both types of alarms.

Position control keypads near all entrance doors. Allow a 30-second delay for entering and exiting without tripping the alarm.

A magnetic switch keeps a monitored alarm circuit closed when a window is closed. When the window is opened, the circuit opens, triggering the alarm.

Passive infrared motion detectors protect large interior areas and hallways. An alarm is triggered when the monitored area is entered.
